Any love for the 6mm Remington?

[LR338nut]

I have a older Rem 700 ADL in 6mm Rem, a bunch of ammo, brass, bullets, and dies. Im thinking of making it into a light weight LR rifle, put a HS LTR stock, BDL bottom metal, and new barrel on it. I have every other caliber in a long range set up except for a 6mm, I was considering a 243 or 243AI.
Should I keep it as a 6mm Rem since I have all the components and dies?
What does everyone think of the cartridge for long range use?

 

[JGorski]

Here's some typical groups from my 6mm REM, very accurate for factory rig. If you're going longrange id opt for a heavier barrel, 41grs RE17 or 42.5-43grs 4000MR work very well with 105s. 3.5" at 600yds last August.

Definitely keep the 6mmREM!!

6mm Remington is a fabulous cartridge. 6mm Rem Ack ain't no slouch either!

 

[smirker]

I have a Rem. ADL in 6mm. Love this gun! It is a short action gun and only shoot 100 gr.Sierra's in it.

I have often wondered about the 6mm remington. It has much more case capacity then say my 6X/XC and a .243. Is a 6mm remington a barrel burner? What velocities do you get out of the 105's or 115's

 

[Huckleberry75]

6mm Rem is an awesome cartridge. Shot my first several deer with Dad's ADL.

My 6mmAI is very close to the top of my "Favorites" list. Damn fine cartridge.

From the trajectory figures Im getting about 2950 from the 105s, could get more but wont be as accurate either. 24" tube.

No it's not,
Ive got over 1500 rounds thru mine, rifling still looks very good, throat is a bit worn, I still get rifling marks when seating bullets, but thats to be expected.

 

[Quack303Head]

You could punch it out to a 6mm crusader! That's one little bad a** cartridge.

Can you spell AI?

Ackley Improved?

 

[jakelly]

6mm Rems are "known" to get better barrel life than 243 wins. The 6mm AI in a long action throated for 115s is on my short list of favorites.

 

[anthonylapoint]

The 6mm AI/Crusader sounds like an unbelievable round. Better barrel life and flatter than a .243, sounds like a winner. Maybe when my 6x barrel shits out......hmmmmm

So, the AI and crusader are just punched out to except 115's? Is there a body taper in either?

I have a Cooper M22 in 6mm Rem and it is definitely one of my favorite all time cartridges. It shoots .5 MOA or better and is the second most accurate factory rifle I have ever owned (topped only by my TRG-22 that cost twice as much). I have about 450 rounds through it and have seen only .001" of throat erosion so far.

I especially like this chambering for hunting due to its accuracy, flat trajectory, wide bullet selection and flexibility. Great for everything from wood chucks to deer. I wouldn't be affraid to use the 6mm Rem on larger game as well.

I used it in a 600 yd F-class shoot once just for shits and giggles and managed to score a 199 out of 200 with it. And that was with 95gr Berger VLDs, a 3 lb trigger, a Zeiss Conquest 6.5-20x50, shooting off a bipod with a rolled up T-shirt for a rear bag. I have only been able to tie that score once with my purpose built F-class rifle shooting 6BR and have yet to top it. I have been tempted to build a serious F-class rifle around this chambering.

All things considered, I'm surprised the 6mm Rem hasn't generated more interest as a tactical comp gun. Probably becuse it needs a long action to run the heavies from a mag, but I don't consider that a deal breaker.

But what if you had a rifle throated for the heavier bullets, so the pressure ring would be at the bottom of the neck when u seat the bullet and the ogive would be very close to the lands. Surely this would seat those longer bullets deep enough so you could load them from the mag. Or not? I know my factory 700 has a long throat and when I seat 95VLDs into the lands there isnt much bearing surface in the case, a shorter throat would be in order then.

You could do that but you would be sacrificing some case capicity and the extra capacity is one of the things (but not the only thing) that makes the 6mm Rem stand out from other chamberings like the .243, 6xc, 6 creedmoore, etc. To get all the the 6mm Rem has to offer, you really need a long action, IMO.

Another draw back might be lack of high quality brass. I believe Remington is the only source for brass, and while their brass isn't all that bad it isn't on par with Lapua.

i have an old ruger m77 that my grandpa got in the 60's it loves 95 grn sst and is a joy to shoot other than the trigger must be at about 15 pounds

Hey there are a few 6mm barrels for sale in the classifieds here right now, in case you didn't see. http://www.snipershide.com/shooting/showthread.php?t=179305

 

[cmh2007]

I have an older 6mm in a model 700 ADL that i am fixing to transfer into a BDL stock for my wife, it shoots accurate enough to teach her long range, and it recoils soft enough that she can shoot it comfortably.

Not really, the only thing protruding into the case below the neck would be the boattail, never mind, just did some measuring and doing that with a 95 or a 105 VLD, you wouldnt have to seat them that deep since the 6mm has such a long neck, but if I were having 6mmREM barrel done id have Kiffer make me a reamer so the oal of a 105VLD would be about 2.810" with the bullet seated .010" into the lands, and there's your short action.

 

[JGorski]

Oh, and Win does make 6mmREM brass. I have 200pcs. though that was bought a few years ago. As far as I know they still make it I should say.

 

[hohlspitz]

The factory 6mm Rem case holds approximately 54.4 grains of H2O to the top of the mouth of the case.

The neck on the standard 6mm Rem is 0.351" in length. If you use a .308 Win. detachable magazine without the spacer you can seat the 105/115 bullets to 2.940" OAL. This leaves about 0.340" of shank in the neck with the rest being boat tail. Only the boat tail protrudes into the shoulder. This is with the longest 6mm 105 gr. Lapua VLD bullets that I have.

Lacking the detachable magazines, you can use a Wyatt's extended magazine box for BDL rifles.

The 6mm GAP Crusader holds approximately 61 grains of H2O to the top of the mouth of the case. This is accomplished by blowing out the shoulder diameter, reducing the case taper and sharpening the shoulder from 26 degrees to a 32 degree angle. The capacity allows the reloader to accomplish velocities of 3100, 3200 and 3300 FPS with the slower being important these days for tactical matches with speed limits.

Quality brass can be had by fireforming the Remington or Winchester brass then cleaning up the cases as usual. But if you think this is not good enough then there's brass available from RWS (6.5x57) and Norma (7x57) which can be modified to work with this chamber.

There is a significant amount of reloading data found in a couple of good threads on the Hide by current owners of rifles chambered for this cartridge. I think George posted some photographs in the original thread but I'd have to find my copies in order to post some myself.

Regards.

Built a 6mm AI based on a long action, throated the barrel to seat the bullets long. Basically it's a 600 yard rifle with the 1-10 twist and 90 gr Scenars, with authority.

Wouldn't bother building one on a short action. Personally I view the short action as a bit of a sacred cow. Seat VLDs or ultra VLDs long and they just don't fit well, requiring single loading. But the 6mm feeds out of a long action mag just fine.

Brass has never been an issue. I've used 7 X 57, 6.5 X 57 and .257 to form brass when factory 6mm wasn't available. Winchester .257 works fine.
